AWS DVA · DVA-C02
The AWS Certified Developer - Associate (DVA-C02) validates your ability to build, deploy, and debug cloud-native applications using AWS SDKs, the CLI, and core services like Lambda, DynamoDB, and API Gateway. For developers it is one of the most recruiter-recognized credentials in cloud hiring — and at 720 out of 1000 to pass, with scenario questions that punish surface-level knowledge, a single failed attempt costs you the $150 fee plus a wait before you can re-sit. This page breaks down exactly what the exam tests, how it's delivered, and how to get it done right the first time.
Pay Only After You Pass
No upfront fee — you settle only after your verified passing result. We advertise guaranteed results — 100% pass guaranteed or money back.
How the DVA-C02 is built — at a glance
65
A mix of multiple-choice (one right answer of four) and multiple-response (two or more correct of five-plus). 50 questions are scored; 15 are unscored research items that are not flagged.
130
Roughly two minutes per question. There is no penalty for wrong answers, so flag the hard scenarios, finish the bank, and come back rather than stalling.
720
Scored 100–1000 using statistical scaling, so 720 is not a flat 72%. The exam is compensatory — strength in one domain can offset a weaker one.
Most items are scenario-based: a short application problem followed by candidate solutions, where two or three options are technically valid and you must pick the one that best fits AWS best practices, cost, or least-privilege security. Expect heavy emphasis on Lambda, DynamoDB, API Gateway, S3, IAM, SQS/SNS, and CloudFormation/SAM.
Your result is reported as pass or fail against the 720 scaled threshold, with a full score report delivered through your AWS Certification account, usually within five business days. A per-domain performance breakdown shows where you were strong or weak, but only the overall scaled score determines whether you pass.
Four official domains — bars show each domain's share of your scored content
The largest domain. Writing application code with AWS SDKs and the CLI, building serverless functions with Lambda, working with DynamoDB and S3, and designing event-driven patterns using SQS, SNS, and EventBridge.
IAM roles and policies, least-privilege access, authentication and authorization with Cognito, encryption with KMS, and managing credentials with Secrets Manager and Parameter Store.
Preparing and deploying applications with CI/CD pipelines, CodePipeline, CodeBuild, and CodeDeploy, plus deployment strategies and infrastructure as code via CloudFormation, SAM, Elastic Beanstalk, and container services.
Root-cause analysis with CloudWatch logs, metrics, and X-Ray tracing, optimizing application performance, and implementing caching, retries, and observability across distributed services.
Because the exam is compensatory, a strong Development and Security profile can carry a weaker Troubleshooting score — but the two heaviest domains together make up nearly 60% of your marks, so SDK fluency and IAM security are where most candidates win or lose the exam.
Two ways to sit the DVA-C02 — and what to expect on test day
You sit the exam in a quiet, monitored room at a Pearson VUE center. Staff verify your government-issued ID, store your belongings, and watch the room. The on-screen exam runs in a locked-down environment with no access to outside documentation, and the fee is $150 USD.
You take the exam from a private room at home or office, monitored by Pearson VUE's OnVUE software with a live proctor. You'll do a webcam room scan, a photo ID check, and a system test beforehand. The fee is the same $150 USD, and you must close all other applications before launch.
A valid, unexpired government photo ID whose name matches your AWS Certification account exactly. The proctor captures a photo and verifies your identity before the exam unlocks.
A clear desk, no second monitor, no phone or notes within reach, and a 360° webcam scan of the room. No one else may enter, and you must stay alone for the full session.
No scheduled breaks on the online format — once you start, you stay seated and on-camera. Talking aloud, leaving the frame, or looking away repeatedly can pause or void the session.
The DVA-C02 is built for engineers writing code on AWS
No mandatory prerequisite — but real hands-on experience is assumed
Difficulty: The DVA-C02 is widely rated moderately hard. The traps aren't the syntax but the service-level detail — Lambda concurrency and cold starts, DynamoDB capacity modes and indexes, IAM policy evaluation, and which deployment strategy fits a given scenario. Most candidates invest 60–120 hours of focused prep, which is exactly the kind of pressure point our help is designed to remove.
